Computer Training Excuses - No ExcuseYou wouldn't go to a doctor who had never been to medical school, or hire a lawyer who never studied law. One side-effect of a world advancing as rapidly as ours is that fields are becoming more and more specialized and narrow. People can no longer get by on general knowledge in their careers, something I found out for myself not too long ago. I'd been out of high school for two years, scraping by on my own and picking up scraps of programming as I went. I saw all of the self-taught programmers breaking into the IT industry, and I hoped to do the same. After all, IT is one of the few industries out there where being creative and a quick learner is more important than a degree.

How to be a Programmer - Programing training To be a good programmer is difficult and noble. The hardest part of making real a collective vision of a software project is dealing with one's coworkers and customers. Writing computer programs is important and takes great intelligence and skill. But it is really child's play compared to everything else that a good programmer must do to make a software system that succeeds for both the customer and myriad colleagues for whom she is partially responsible. In this essay I attempt to summarize as concisely as possible those things that I wish someone had explained to me when I was twenty-one.

What Programming Language To Learn - Programming LanguagesOne of the most common questions we hear from individuals hoping to enter the IT industry is, "What programming languages do I need to know?" Obviously this is a complex question, and the answer will depend on what field the questioner is going into. Many programming languages are taught during courses used to obtain a computer information science degree. However, those already in IT know that the greatest skill you can have is to be a jack-of-all-trades. A well-prepared worker can switch between computer programming jobs with only minimal training, thanks to a wide knowledge of multiple programming languages.

What is JavaScript?

A Web scripting language that is used in both browsers and Web servers. It is not a Java technology.

A scripting language developed by Netscape to enable Web authors to design interactive sites. Although it shares many of the features and structures of the full Java language, it was developed independently.

JavaScript can interact with HTML source code, enabling Web authors to spice up their sites with dynamic content. JavaScript is endorsed by a number of software companies
And is an open language that anyone can use without purchasing a license. Recent browsers from Netscape and Microsoft support it, though Internet Explorer supports only a subset, which Microsoft calls Jscript.


Tips

HEAD or BODY -- Where To Put JavaScript Code

Ifit will work that way, put the JavaScript code in the HEAD section of your page.Although not all JavaScript is required to be there, code in the HEAD section isloaded and ready before the web page completes loading.

Ingeneral, if the JavaScript must be available to the page on or before itcompletes loading, it must be in the HEAD area. Otherwise, it may be in the BODYarea at or above the point where it will be utilized.

Converta JavaScript Variable to Upper Case

Thefollowing example shows you how to convert a variable in JavaScript touppercase. When performing If string comparisons you should always convert thestring variable to upper or lower case and then compare it to all upper or lowercase literals or variables. This will eliminate a lot of run-time programanomalies

<scriptlanguage="JavaScript">
var x = "Bill";
x = x.toUpperCase() // Use toLowerCase() for lower case conversion
alert(x)
</script>

Displayinga message in a pop-up window

JavaScripthas a function called alert()which pops up a window with the message you pass to alert() as parameter. The simplest example of usingthis function is to display a message when your page loads. To do this just putthe following code right after the <BODY>tag (or within the <HEAD>tag or where ever you want).

<SCRIPTLANGUAGE="JavaScript">
<!-- Hide from older browsers
alert("Press Ok to start formatting your hard disk");
// end hiding -->
</SCRIPT>

Thisis a great way to scare off visitors to your page but let us see if it'spossible to something more useful. What if we want to pop-up a message box whenthe user clicks on a link. It so happens that this is indeed possible.

ViewSource Code Link

Letyour visitors view the source code of any web page, on your own site orelsewhere, by clicking a link or button.

Examplelink:

<ahref="view-source:http://willmaster.com/">
Viewsource of willmaster.com home page</a>
Examplebutton:
<form>
<input type="button" value="Viewsource of willmaster.com home page"
onClick="location.href='view-source:http://willmaster.com/'">
</form>

Inboth instances, change the URL to the URL of the web page you are providing thesource code to, and change the prompts to your preferences.

Automatically opening awindow

Whenyour readers enter a page you can automatically open a new, often smaller windowdisplaying another WebPages. This trick is often used to bring up an advertconsole or control panel. You can specify the size and position of the windowand turn off some or all the normal features of a graphical browser: scrollbars,toolbar, location bar, directory buttons, status bar and menu bar. The width andheight are specified in pixels and the position is specified in pixels from thetop-left of the screen. Place the code in between the <HEAD></HEAD> tags of your document.

<SCRIPTLANGUAGE="JavaScript">
<!--//hide script from old browsers
window.open("newpage.htm", "new_win", "resizable=yes,scrollbars=no, toolbar=no, location=no, directories=no, status=no, menubar=no,width=520, height=200, top=5, left=5")
//end hiding contents -->
</SCRIPT>

ResizingYou Current Browser Window

Usethis trick to resize the window size of your current browser. You can associatethis JavaScript function call with any HTML Object event.

<bodyonload="javascript:window.resizeTo(300,300)">

"Printthis Page" Link or Button

Whenyou want to remind people to print a page, you can make it easy for them with alink. The code presented here works with most JavaScript enabled browsers andwill produce a link that functions like the browser's "print" button.

Asimple text link (can also serve as an image link):

<ahref="javascript:print()">Print this page!</a>

Aform button with the same function:

<form>

<inputtype="button"

value="Printthis page!"

onClick="javascript:print()">

</form>

Howto Redirect a URL to another Frame using JavaScript

Thiscode can be used to redirect the current web page to a URL of a different frameon the current page.

<scriptlanguage="JavaScript">
parent.frame2.location.href="http://www.katungroup.com"
</script>

Creating a scrolling textbox

Byusing small pieces of JavaScript you can create a scrolling text in a text box.First we need to insert the scrolling text JavaScript code in the HEAD of the page.

Thenwe need to set the text box scrolling once the page has loaded. This is done bycalling the JavaScript function by using the onLoadevent handler in the BODYelement. Note you can also include any other of the normal BODY attributes, such as BGCOLOR, alongside the onLoad event handler.

BODYonLoad="banner()">

Andfinally we need to actually insert the text box into the page.

<FORMNAME="thisform">
<INPUT TYPE="text" NAME="thisbanner"size="40">
</FORM>

  • JavaScript is the most widely used language with HTML. And the second most common language on the web.
